If you are looking for the most reliable diesel engines, today you will be informed. Every engine is an engine and not everyone can be on our list, so we went to unveil the best and latest studies on automobile reliability and understand which diesel engines have surprised consumers positively.

The reliability of the brand is one of the essential issues when purchasing a new car and, when it comes to diesel engines, any positive recommendation is more than welcome. However, there is a need to share this loyalty in the choice of engines through several fundamental aspects. The design of an engine is elaborated through a continuous study always present by the manufacturers, using the best available technology and reflecting the requirements of the legislation applied in this regard. The entire laboratory test allows to evaluate the reliability of the essential components and parts that guarantee the performance, longevity and emissions of the engine.

In this way, discover some of the most reliable diesel engines on the market, some of which have been on the market for more than a decade with the status of authentic “veterans”.

TOP 10 MOST RELIABLE DIESEL ENGINES ON THE MARKET, CURRENTLY

1. BMW 5 Series (530d and 535d engine)

In terms of reliability, BMW, like most German brands, has lost popularity. However, there are two engines that have stood out positively and they are the 30d and 35d engines, which equip both the 5 series and 3 series 2018 cars.

These 2 engines have been shown to be extremely reliable, and with regard to diesel vehicles, these are possibly the most resistant and robust engines.

As a curiosity, the BMW 5 Series presents results worthy of a sports car, reaching 100 km / h in 6.8 seconds. A mix of sensations patented by the Bavarian brand that has always impressed with family cars that have managed to translate sports efficiency.

2. Volvo V60 2.0 D3

From Volvo we went to discover the 163 hp engine of the V60 model. A 163 HP CV 2.0 D3 diesel engine that gives Volvo a few extra dots, a brand that, although recently installed, manages to guarantee a good reputation with regard to its reliability.

This 5-cylinder diesel engine van releases 400 nm from 1400 revolutions, which adds a degree of sporty driving at low speeds, always combined with the safety and comfort of the driver and his passengers.

3. Volkswagen Golf IV 1.9 TDI

Although, unfortunately, they launched some more problematic models to the market, Audi and Volkswagen have always been referred, after several studies, as being the preferred car brands of the Portuguese.

Overall, Volkswagen's Gold IV 1.9 TDI model has added up. This diesel engine was launched with different powers: when it started to be marketed in late 1997, there were already two powers: the 1.9 TDI 90 hp and the 110 hp. Two years later, already with a 6-speed gearbox, the 1.9 TDI 115 hp appears, and later, in the same year, the 130 hp version comes out, also with the 6-speed gearbox.

4. Audi A6 1.9 TDI

If you're looking for Audi's most reliable diesel engines, then skip seven feet from 1.4 TSI engines, but focus on others. Notably in this Audi A6, either in van or limousine versions.

This model is of the second generation of the A6 (type 4B) and started to be commercialized in the beginning of 1997, having been later launched other versions.

As with the Golf IV, this generation of the Audi A6 had a variety of diesel options. The 1.9-liter diesel engines offered power of 100, 115 or 130 hp. This was considered by many to be one of the most reliable diesel engines of the 1990s.

5. Mercedes-Benz C 220 D

The Stuttgart brand is considered to be one of the “mothers” when it comes to creating diesel engines. The reliability of its engines inscribes it on the pages of automotive history as being exemplary both in its reliability and in its performance.

With this 220D engine and the 2100-cylinder engine with 143 hp, Mercedes equipped both the C-class and other models of the brand, doing justice to its status. It is an engine that was marketed in the C generations, between the years 2000 and 2007, and which, even today, stands out in the number of units sold, quite visible on our roads.

6. Citroën C3 Picasso 1.6 HDI

Even though the Citroën brand has never reached the top of the charts when it comes to automotive reliability in the context of electronics, the truth is that problems related to the mechanics are almost insignificant, appearing with little regularity, causing no owner to open a bankruptcy because, after all, Citroën mechanics are very simple and very balanced.

Consumers see the Citroën C3 Picasso 1.6 as a good car and the most reliable diesel engines include the C3 Picasso 1.6 HDi with 90 hp and the 1.6 HDi with 110 hp FAP. It should also be noted that the design of this engine block was the result of a partnership between the PSA Group and BMW, with the commitment to be able to equip various models, both from the two manufacturers and from others, namely Mini and Volvo.

7. Citroën C4 1.6 HDi diesel

As a curiosity, this model won the award for "World Car of the Year in Design 2006", surpassing the BMW 3 Series and the European version of the Honda Civic / Civic Hybrid.

The C4 features hybrid engines of two powers: 1.6HDi 92hp diesel and 1.6HDi 110hp diesel that definitely deserve to be highlighted in our list of the most reliable and environmentally friendly diesel engines.

8. Seat Toledo 1.9 TDI

In recent years, the confidence of Portuguese consumers has gone hand in hand with the VAG group, which includes the Skoda and Seat brands.

The round of applause and merit goes to the Seat Toledo model (2001 model) and its 1.9-liter Turbodiesel TDI engines, which, at that time, began to win the interest of consumers for an exemplary record of reliability and a approach to quality and robustness associated with German brand models.

9. Honda Civic 1.6 i-DTEC

Japanese brands acquired a status of reliability already in the 60s with many different models. Honda represented this merit very well with the Vtec engine series in the 90s and still continues to represent it with the new 1.6 i-DTEC, consolidating itself as one of the best diesel engines of the moment, which makes this compact a dynamic car and now optimized to reduce consumption.

Its quality and reliability is proportional to its price, surpassing the value of some best-selling compacts, such as the Seat Léon, Renault Mégane and Volkswagen Golf.

10. Renault Type K

It is currently one of the best-selling engines in the world. The 1500 cc block of 90, 110 or 160 horsepower equips not only virtually the entire Renault range, but also almost the entire Nissan range. This is also the same block that equips Mercedes Class A, B, CLA and GLA, and also Mercedes Citan.

If you are aware of the car market, you have certainly heard enough people criticizing the fact that these Mercedes models are equipped with a Renault engine. Although the performance is not impressive, the great truth is that consumption, reliability and sales figures are impressive, so we can't help but consider this one of the best diesel engines ever.
